To all whom it'may concern:

Be it known that I, LOUIS A. CASGRAIN, a citizen of the United Statesntesid ing at Winchester, in the county of Middlesex and State of Massachusetts, have invented an Improvement irfWork-Gages for Nailing-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to a novel work-gage more particularly designed for use in connectioriwith apparatus for inserting fastenings into boots and shoes in the manufacture thereof.

During the operation of'inserting the fastenings into the work the latter is held upon a work-support or horn, and a gage is usually employed to assist the workman in guiding the work as it is turned upon the work-support and fed to present different portions to the fastening inserting mechanism. The work-gage forming the subject matter of my present invention is constructed and arranged to engage, preferably, the upper of the boot or shoenear the sole.

The gage is especially intended for machines used for heel seat nailing. The heel seat portion of the sole extends for an irregular distance beyond the counter portion of the upper so that it is impracticable to use in heel seat nailing machines a gage arranged to contact result in an irregular placing of the nails and frequently: in the driving of the nails entirely outside of the counter with the edge of the sole, as the use of such a gage would" portion of the upper. While, however, the gage is especially intended for use in heel seat nailing, it is obviously well adapted for use in any kind of work in which the same conditions exist, that is, where it is impracticable to guide the shoe by the edge of the sole and therefore preferable to guide it by a gage which contacts with the upper. This form of gage is also frequently preferable in machines in which the horn is periodically depressed to allow the work to'be fed. In

machines used for heel seat nailing'or for attaching soles, it is necessary, in using a gage which contacts with the edge of the'sole, to have it so thin that there is danger that when the horn is depressed the sole will getaway from the gage and not get properly into place again when the horn again rises. I have provided the gage with a work-engaging member, preferably rotatable, and have made provision for permitting the gage to move up and down with the work as the latter fol lows the up and down movement of the horn or worksupport, with the extending heel seat portionof the sole resting continuously on the top of the gage, thereby preventing any abrasion or rubbing of the upper while incontact with the gage. Adjustable means are vided for regulating the up and down movement of the gage in accordance with the movement of the horn and the character of the work. a

This work-gage is shown in operative connection with cation Se. No. 687,682, for nailing machine, filed August 4, 1898, from which application the present application is a division.

Figure 1 is a right hand side elevation of the head of a nailing machine, with one embodiment of my present invention shown in operative connection therewith, the machine being at rest; Fig. 2 is an enlarged view in side elevation, of the work-gage and its supporting bracket, the view being taken from the side opposite a'machine forinserting metallic fastenings in my applito that shown in Fig. 1, and Fig. 3 is atop or plan view, also enlarged, of the work-gage and its supporting bracket.

Referring to the drawing, Fig. 1, A represents part of the head of a machine for inserting fastenings, provided with coiiperating clutch members A, A means for inserting fastenings in the work, and a presser P, all substantially as shown and described in United States Patent No. 310,816, dated January 13, 1885, the

upper end of awork-support or him: H being shown in Fig. 1. W

1 The work-gage is herein shown as comprising a work-' engaging member in the form of a roll m preferablyhaving a peripheral covering m of some soft or yielding material such as felt, rubber, etc., and slightly con- I vexed axially, see Fig. 2. v

A plate or bracket m for sustaining the work-gage is adapted to be secured to the usual gage'carrier R,

'see Fig. 1. The gage carrier is adjustable to vary the distance between the gage and the driver of the machine to determine the distance from the edge of work at which the nail or other fastening is to be inserted.

The bracket in has a tubular bearing m, Figs; 2 and 3,

through which is extended the reduced portion m of a shouldered bolt m 5 The body portion of the bolt 1 passes through a hub m of an arm m, on theouter end of which the work engaging member m is rotatably mounted. A nut 25 on the reduced portion m of the bolt holds the latter rigidly in place in the bearing'm of the bracket, 'the armmf havinga rocking movement vupon the bolt as aiulcrum. 'One end ofa spring 's'is held in a housing m on the, bracket, Fig. 2, and the other end of th'e'sprin'g extends beneath a lug m? on armand the roll m thereupon.

the arm m, the springnormally acting to elevate the Asshown clearly m rage the sacram nts a depending, portion" or m in its upright edge with a recess or notch 113, adapted to receive one or the other of a series of different sized stops 50, 51, 52

' I have herein shown these stops as radially arranged ears of different width connected by a combined clamping and supporting bolt m with the side of the arm m adjacent the web m the width of the largest ear 52 being slightly less than the length of the notch m..

, tical path is permitted, and when the apparatus is thus adjusted'the roll m is permitted to have its greatest rising and falling movement. The ear 51 is a little wider than theear 50, and when placed within the notch permits less movement of the arm in and the roll, while the ear 52 is so wide that a very slight play is allowed between the stop and ends oi the notch andonly the minimum vibration of the work gage is permitted. 4

The spring 8 is purposely made light, its strength being suflicicnt to retain the work-gage in operative position without opposing any material obstacle to the movement of the gage with the work as the latter follows-the up and down movement of the horn.

By rotatably mounting the work-engaging member of the gage and permitting it'to move up and down, as described, the contacting part of the upper of the boot or shoe is not rubbed, abraded or otherwise injured, while a laterally firm gage is provided for the. work during the manipulation thereof by the operator.

Having described my invention what I claim as new and desire to secure by Letters Patent is:--

1. A work-gage comprising a yieldlngly-controlled workengaglng member adopted to guide the work and movable In a vertical path, and adjustable means to positively regir late such movement in both directions.

2. A work-gage comprising a spring-controlled support tively regulate the extent of movement or the latter in both directions. B

l. in a mechanism for inserting fasteners. a presscr, a bracket adjacent thereto, a spring controlled arm pivotally mounted on the bracket and vertically movable relatively to said presser, a rotatable work-engaging member on the arm, and llJOilHS'tO adjustubly limit the movement oi. the arm.

5. In a mechanism for inserting fastenings, a yieldingly controlled work-engaging member, sustaining means therefor, ii plurality of. different sized stops movably mounted on one of said parts, and means on the other of said parts constructed and arranged to engage said stops singly to limit the movement of said work-engaging member.

6, In a mechanism for inserting fastenings, a bracket, a yieldingly controlled arm connected therewith, one of said parts having a recess, a plurality of different sized stops movably mounted on the other 01 said parts to entersingly said recess to limit the movement of said arm, and a work-engaging member carried by said arm.

In a mechanism for inserting fastenings, a bracket, spring-controlled arm pivotally nountcd on the bracket, a plurality of connected stops of different width movably mounted on one oi said partsto enter singly a notch hr the other, to limit the movement ot the arm, [one 01' said parts having a notch, and a rotatable work-engaging member carried by the arm,

8. A work-gage comprising a bracket, 21 spring-controlled urm pivotally connected therewith, a plurality of connected stops of different width' movabiy mounted on one, to cooperare singly with a notch in the other, of said members, to adjustably limit swinging movementof the arm, one of said members having a notch, and a. work-engaging rncrnlwr carricd by the arm.

. 9. A work-gagecomprising a bracket, a spring-controlled arm pivotnlly connected therewith, a plurality of con nected, radial stops of different width rotatably mounted on one or. said members, to coliperate singly with a notch in the other. member, to zidjusmbly limit swinging movement 01' the arm, one of said members having a notch, means to retain the stops in adjustment, and. a rotatable work-engaging member carried by the arm.

10. A work-gage comprising ayieldingly controlled workengaging member mounted to have movement-in a vertical path only, and adjustable means to regulate the amplitude of such movement. v i

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
